Two-for-One Camera
TELEVISION’S fascinating forward march resulted in another development recently when Du Mont Laboratories, Inc., Clifton, N. J., announced the Electronicam, an amazing new two-for-one camera which enables standard black-and-white TV programs to be broadcast while a high-quality film of the same program is simultaneously recorded in black-and-white or color.

A 31-pound set steals a march on the industry

The gentleman shown above luxuriously sprawled in his bathtub is enjoying the newest thing in television—a portable set. (He also is risking electrocution because either a radio or TV set can kill a wet bather if he so much as touches it.) His set, made by the Sentinel Radio Corporation, has a small collapsible antenna, a 7-inch screen, and sells for $206.90 complete. It is easily transportable (below), needs only a socket with alternating current to operate both indoors and out, provides excellent reception which is comparable to that of much more expensive receivers.
